Mixing tube (cone) for epoxy resin or similar. Can be used with the epoxy mixing "pistol" or without it. It is designed to fit standard two-component glues and substances such as the Wurth ESK-50 Fast bonding adhesive.
I have combined two models:

+

and modified the result model to fit my purposes.
It is field-tested, it works OK.
Print it standing on the bed by its base. It works fine but be careful when handling - it is prone to breaking.
Basically any material is fine - I used transparent PLA.
Resolution 0.2mm is fine.
The author remixed this model.
